SPECIFICATION forming part of Letters Patent No.\523,128, dated J'uly 1'7, 1894. Application tiled September 25, 1898. Serial No. 486,406. (No model.)

To CZZZ whom t may concern:

Be it known that-I, KAJETAN Mosoicxi, a subject of the Czar of Russia, and a resident of Warsaw, Russia, have invented certainv new and useful Improvements in Engines, of4 which the following is a specification.

My invention has relation in general to steam or other fluid engines; and it relates more particularly to the general construction and arrangement of the engine adapted to different uses or purposes. A

The principal objectsl of my invention are first, to provide a comparatively simple, durable and effective steam or elastic iiuid engine; second, to provide a rotary engine for pumping and other purposes so constructed and'arranged as that positive movement and effective action of the parts thereof are insured and the engine so constructed and arranged as that the same has but a single dead center point and the piston adapted to be perated so that a single revolution of the same eects a double revolution of the crank of the engine; third, to provide a rotary engine having a steady7 and uniform action or movement; fourth, to provide an engine so constructed and arranged as that each piston is adapted to alternately control the influx and efflux of steam or other fluid and to act as a working member of the engine; fifth, to provide an engine having two pistons so arranged for operation as to move alternately for controlling the actions thereof; sixth; to provide an engine with a fixed cylinder and with two pistons alternately actuated and having but a ysingle dead center point; seventh, to provide an engine having a movable cylinder and two pistons alternately actuated and arranged so as to be afforded two different rates of'speed for respectively serving as the working member of the engine and for permitting of the entrance and exitv of theelastic fluid to and from the cylinder of the engine; eighth, to provide an engine having two pistons with a single dead center point and the pistons thereof .arranged for operation so as to be afforded different rates of speed in the respective movements thereof; and ninth, to provide an engine in which the effective action and speed thereof are appreciably enhanced, thereby adapting the engine to many different uses or purposes.

tional view of the same on thelines 3 4 and 5 6 of Fig. 1. Fig. 4, isa similar view on the line 7-16, of Fig. 1.v Fig. 5, isalongitudinal central section of a rotary pumping engine in a modified form, embodying features of my invention. Fig. 6, is `a top or plan view of .the pumping engine of Fig. 5. Fig. 7, is a cross sectional view of the pumping engine on the lines 17-18 and 19-20 of Fig. 5; and Fig. 8, is a similar view on the line 9-16, of Fig. 5.

Referring to the accompanying drawings with special reference to Figs. 1 to 4, which illustrate an engine having two pistons H' and I, connected respectively with concentric axles L and M. These axles projecting through the inclosing cylinder, A, on the left hand side, have respectivelylitted to orformed integral with them cranks Z and m. The crank fm', has a pin m2, and the crank Z', has a corresponding pin Z2. These pinsl are respectivelyinserted through bearings provided in lever-arms or connecting rods O and P, having bosses O and P', which are concentrically mounted on the pin or stud C4, which SoV projects from the counter-weighted crank C',

carried by the shaft C.

C5, is a counter-weight of the crank C.

The shaft C, is mounted in bearings r and S', provided in the top of the pedestals or standards R and S, and this shaft carries a fly-wheel C2, and. a Vpulley O3, for the reception of a belt, not shown, whereby motion may be communicated to a machine for effecting the actuation thereof. The crank Zis connected to the lever-arm or connecting-rodP, by means of the pivots or stud-pins p and Z4, and the belt Q.

Fixed to the counter-weighted crank C', is

IOO

a cam C6, as illustrated in Figs. l, 2, 5, (i and '7, for maintaining the small eccentrically arranged pins Z3 and m3, of the crank arms Z2 and m2, alternately in engagement with the peripheral surface of the cam in the rotation of the shaft C, and therewith of the counterweighted crank C', as fully shown in Figs. 3 and 7. These pins Z3 and lm, may be as small as possible, for the reason that they are employed merely to prevent accidental displacementor dislocation of the arms Z2 and m2, for the reason that they are alternately in engagement with portions of the cam (lf3-in the rotation of the cranks Z and m', in connection with the connecting rods O and P.

The bulk of the single moving parts of the engine are so arranged as that the mechanism thereof is maintained continuously in equilibrium. The outward formation of the cylinder A, as illustrated in Figs. l to 4, is in the form of a truncated cone, and the same tits snugly into a casing D, which is bolted to the foundation or platform G, as illustrated in Figs. 1 and 5. The cylinderA, is provided with two ports a and a2, as shown in dotted lines in Fie. 4, and they are placed close to one another. In the casing D, are provided three ports CZS, Z4 and d5, of which the two outer ports d3 and d5, communicate with each other and the outlet or exhaust pipe (Z2, While the center port d, is in direct communication with the fluid supply pipe LZ.

The pistons I-I and I, are arranged so as to snugly fit the internal surface ot' the cylinder A, by means of metallic strips h2 and 2, caused to bear firmly against the surface of the cylinder A, by means of springs 7i and 7i. These pistons where they bear against one anotherare likewise fitted with packing strips h3 and is. The cylinder A, can be turned round its axis so as to regulate the cut oft, and the direction of rotation of the engine, that is, if the cylinder is turned sufficiently to bring the port a2, as illustrated in Fig. 4, into communication with the exhaust port d5, while the port a', is in communication with the supply port d, the direction of rotation will be reversed, that is, assuming that the ports a and a2, were respectively in their former positions in communication with the ports (Z3 and d4.

If it is required to reverse the engine, the cylinder A, will be turned by means of the handcrank t', mounted on the shaft T, which is provided with a worm B', meshing with a toothed segment a3, as illustrated in dotted lines in Figs. 3 and it, and connected with the cylinder A. When the crank Z', is turned, the worm B', meshes with the segment a3, and revolves the cylinder A. The range of movement through which the cylinder must be turned to regulate the eut off is controlled by means of a governor U, as illustrated in Fig.

`1. This governor U, is driven from the main shaft C, bymeans of the bevel-wheels B2 and B3, having on its casin g u2, two plates or disks a4 and a5, revolving along with 1t. These plates or disks have spirally cut teeth p and p', facing one another, and into one or the other of these teeth the cog-wheel U6 meshes, according as the casing u2, rises or falls in the movement of the engine.

u', is a spring and u? and as, are arms carrying centrifugal balls.

The spiral teeth are of opposite action, that is to say, one spiral is arranged to run from the center of the disk toward the circumference, while the otherspiral runs from the circumference toward the center. Vtfhen the speed of the engine increases, the casing u2, descends and as a consequence the disk or plate u, comes in contact with the cog-wheel U6, thereby revolving the same and the crossshaft u, and the bevel-wheel u1, on this shaft actuates the bevel-wheel t, turning the shaft ZIO, and the bevel-wheel Z1", as illustrated in Fig. 2, which in turn actuates either the bevelwheel t2 or t3, when in gear, and revolves through the same the shaft T and also the cylinder A. Vtfhen the speed of the engine is decreased, the casing u2, rises and the disk or plate a5, actuates the cog-wheel U6, and its connected mechanism, so as to again revolve the cylinder A.

When the reversal of the engine has been accomplished by means of the hand-crank t', as hereinbefore described, the governing mechanism must be thrown out of gear by the disengagement of the cog-wheel U6, from the teeth of the plate or disk a5, through the fall of the weighted arms a7 and u8, and therewith the casing u2, and so that the cog-wheel -will be out of engagement with both of the said toothed plates or disks. As will be ebserved a space is left between the cylinder A, and its casing D, and which space serves as a steam jacket. Steam is admitted to the space from the port d', through the passages g4, g5 and y, and the water of condensation is conducted through the passages g3, on the opposite side, into the exhaust of the engine.

The engine is provided with a luubricating appliance or apparatus W, from which when filled with oil it flows by means of the pipe connections W' and W2, controlled by valves W3 and W4, to the pistons II and I, for effecting the continual lubrication thereof. X, are drain cocks provided with handles X and X2. Z, is a protector or guard for thc engine.

The pumping engine illustrated in Figs. 5 to 8 inclusive, differs in construction from the engine described with reference to Figs. l to 4:, in so far that the cylinder A, in this instance, is stationary instead of movable, and the outer casing D, of Fig. l, is dispensed with. The inlet and outlet ports a and a?, communicate respectively with the inlet passage ai, and the outlet passage a4. The cylinder A, with its passageways, is, in this case, bolted directly to the foundation or platform G. To prevent thuds when passing the dead center point, the ports a and a2, are tapered or widened out to the lines a5, a, al and as,

IOC

IIO

through which, at the moment when a direct communication is established between the passages a3 and a4, the liquid moves on account of its inertia, uninterruptedly.

The construction and arrangement of ap paratus such l-as hereinbefore described is adapted for use, as a water-motor, ventilator, pump or a steam engine.

The peculiar construction of the engine and the manner in which the parts thereof are connected together are such, that while the direction of rotationof the pistons H an'd I, is always the same, yet at different periods in their revolutions, they travel at different rates of speed, thatis to say, at one period of time, the piston I-I, will travel at a quicker rate of speed than the piston I, and at another period of time, the piston I, will travel f at a greater rate of speed than the piston H.

The piston which for the time being is traveling at a quick rate of speed acts on the crank pin C4, of the shaft C, while the piston, which for the time being is traveling at' a slow rate of'speed controls the entrance and exit of the elastic fluid to and from the cylinder A by the opening and closing of the ports at the proper time to and from the cylinder A. After the quick traveling piston has completed one revolution, it exchanges or assumes the functions of the slow piston, and vice versa.

It will be manifestly obvious that as to minor details of constructiony and arrangement, modications may be made without departing from the spirit of my invention; and hence I do not wish to be understood as limiting myself to the precise construction and arrangement illustrated and explained.
